US consumer sentiment fell to a four-month low in September2,5. The University of Michigan’s Surveys of Consumers index dipped to a reading of 48.12, with the decline driven by inflation worries and high prices weighing on household finances1. The final reading was revised up to 48.1, dropping less than previously estimated3,7. Sentiment declined on the month even as the mood improved from an earlier reading in the survey period6. One account put the drop at 15 per cent against the prior reading5.

Survey director Joanne Hsu said the deterioration was bipartisan4. A separate gauge pointed the same way: the S&P Global consumer sentiment index dropped to 42.7 in September from 42.9 in August, indicating notable strain on household finances10.

Why it matters to investors

The reading widens the gap between the activity data and the survey data. One strategist pointed to a widening divergence in the United States between hard economic data and softer data, with weakening consumer sentiment sitting alongside sticky inflation9. That divergence is what makes the next round of releases consequential rather than routine.

Sentiment has slid sharply in the face of stubborn inflation, mixed with slower economic growth and high interest rates8. The Guardian reported that the administration’s claims about the economy are falling flat with voters as the midterm elections approach8. Durable goods orders were unchanged over the same stretch3,7. The dollar kept rising amid the bond selloff and rate-hike worries as the sentiment data landed7.

What to watch

Fuel costs are the visible channel into household budgets, and pressure from them is showing up directly in the survey commentary on prices1,10. In the UK, households have begun contacting mortgage brokers months early as the strain builds, a pattern that accompanied the fall in the S&P Global index10.

For markets, the sentiment print landed alongside rising yields and the rejection of the Hormuz proposal, a combination that weighed on US equity futures9. The question from here is whether the softer survey data eventually pulls the hard data down with it, or whether resilient spending keeps the two apart8,9. Moomoo noted the monthly survey still registered a decline even where the tone improved later in the collection period6. The Michigan reading remains the reference series, and its September level of 48.1 is the number policymakers and strategists are working from1,2.
